Abstract
The invention relates to a method for the optimised management of a membrane filtration unit based on membrane micro-coagulation, that comprises at least one measurement of the effluent temperature (7), one measurement of the filtration flow rate (8), and one measurement of the trans-membrane pressure (9). The injection of the coagulation reagent(s) is controlled by a unit (U) when the membrane permeability becomes lower than a threshold value, and the interruption of the coagulation reagent(s) injection is controlled when the membrane permeability is again equal to or higher than the stable LpO value before the drop, during a predetermined hold time.
